Ethyl N-[1-(2-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]amino}ethyl)-2,4-dioxo-1,2,3,4-tetrahydropyrimidine-5-carbonyl]carbamate CAS 338409-46-4

Description

Ethyl N-[1-(2-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]amino}ethyl)-2,4-dioxo-1,2,3,4-tetrahydropyrimidine-5-carbonyl]carbamate (CAS 338409-46-4) is a high-purity analytical reference standard with the molecular formula C16H15ClF3N5O5 and a molecular weight of 449.77 g/mol.

The molecular framework of Ethyl N-[1-(2-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]amino}ethyl)-2,4-dioxo-1,2,3,4-tetrahydropyrimidine-5-carbonyl]carbamate (C16H15ClF3N5O5) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
